Impact of physical and physiological factors on arterial function

Clinical and Experimental Pharmacology & Physiology

Abstract

1. Arterial function measurements are increasingly used as surrogate markers of cardiovascular disease and it is important to define which non-pathological factors may influence these measurements. 2. The present study examined the influence of gender, height, body mass index (BMI), waist : hip ratio, heart rate and arterial pressure on pulse wave velocity (PWV), systemic arterial compliance (SAC) and central pressure augmentation index (AI) in 285 normal subjects, 98 males and 187 females, aged 50-82 years. 3. There were significant gender differences in PWV (higher in men), SAC (higher in men) and central pressure AI (lower in men). 4. Both SAC and AI were correlated with height in men and women and height largely accounted for gender differences. 5. Systemic arterial compliance was positively, whereas AI was negatively, correlated with BMI. 6. Both PWV and AI were significantly correlated with heart rate and central pulse pressure. 7. These findings may have implications for cardiovascular disorders. Reduced central arterial compliance and increased central pressure augmentation are potential mediators for the increased cardiovascular risk of short stature. A slow heart rate may contribute to increased central arterial press...Continue Reading

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
